Influence of Pulp Fibers on the Conductivity of Polypyrrole-coated Electroconductive Paper
Electroconductive polymers have gained a great deal of interest because of their physical and chemical properties and their potential industrial applications.However,one of the shortcomings of most conductive polymers is that they are often formed as intractable films that are difficult to process.To overcome this problem,pyrrole was polymerized into pulp fibers by in-situ polymerization process in order to manufacture polypyrrole-coated electroconductive paper.This electroconductive paper is a kind of functional paper which can be potentially used for antistatic packaging material,electromagnetic shielding material,new energy and electrochemical material,sensor and driven material.In this paper,the effects of pulp type,sulfonation degree,delignification degree and beating degree on the performance of electro-conductive paper were investigated.The relationship of pulp types with the surface resistivity of electroconductive paper was revealed.The results showed that the pulp type greatly influences the surface resistivity of electroconductive paper.The presence of sulfonic groups in pulp fibers can decrease the surface resistivity of electroconductive paper.However,lignin in pulp fibers can impede the polymerization of pyrrole.Beating degree of pulp also has some influence on the polymerization of pyrrole,thus the surface resistivity of electroconductive paper.
